Cobalt Blue Holdings Ltd has proposed a name change in line with its diversification strategy, proposing to rename Core Blue Minerals Ltd on the back of an earn-in agreement with AuKing Mining Ltd for the Halls Creek Project.
Halls Creek in Western Australia's north is a large-scale copper, lead, zinc, silver and gold project with significant cobalt potential.
COB says the agreement will allow the company to leverage its extensive metallurgical, engineering and project development expertise to further diversify its portfolio.
“Transformational” step toward resilience
“The Cobalt Blue name no longer reflects the full scope of our business,” Cobalt Blue CEO Joe Kaderavek said.
“As our technical and project development expertise uncovers new opportunities across base and precious metals, a corporate rebrand marks a key milestone.
“While our commitment to delivering a strong battery materials strategy remains unchanged, we are actively expanding our portfolio with high-value projects that have the potential to enhance future earnings.
“The Halls Creek Project earn-in is a transformational step, broadening our commodity exposure and strengthening our resilience against future pricing cycles.
“We see immense development potential at Halls Creek and are well-positioned to unlock value through complementary initiatives — including the development of Australia’s first cobalt-nickel refinery.”
Halls Creek Project
Halls Creek already hosts two deposits – Sandiego and Onedin – with existing mineral resources totalling 89,000 tonnes of copper, 69,000 tonnes of lead, 326,000 tonnes of zinc, 9.2 million ounces of silver and 45,000 ounces of gold.
Importantly, 96% of the mineral resource total sits within the indicated category, offering higher confidence in its mineral bounty.
COB says AKN’s geological modelling has highlighted an opportunity for high-grade extensions and/or repetitions with deposits open along strike and at depth for further exploration.
Drilling at Onedin has also identified a zone of near-surface oxide-transition-supergene copper mineralisation, with very broad intersections including:
- 55.1 metres at 3.5% copper, 1.2% lead, 0.8% zinc and 103 g/t silver from 94 metres, including 16.6 metres at 10.2% copper, 0.5% lead, 1% zinc and 316 g/t silver from 130 metres; and
- 118 metres at 1.1% copper, 1.6% lead, 1.1% zinc and 52 g/t silver from 14 metres, including 21 metres at 2.1% copper and 66 g/t silver from 93 metres.
The project sits within the Kimberley region of Western Australia; just 15 kilometres southwest of Halls Creek and 320 kilometres south of Wyndham port.
The area was historically host to the Nicholsons Gold Mine and the Savannah Nickel-Copper-Cobalt Mine – COB says it has strong logistics support, including established roads and port facilities.
